Viewing the CPU Utilization

The CPU Utilization page contains information about the system’s CPU utilization and percentage of

CPU resources consumed by each stacking member. Each stacking member is assigned a color on the

graph.

The range of the utilization reading is from 0 to 200%. The maximum reading of 200% for a full duplex

connection indicates that 100% of bandwidth of incoming and outgoing connections is used by the

traffic traveling through the interface. The maximum reading for a half duplex connection is 100%.

To open the CPU Utilization page, click Statistics/RMON→ Charts→ CPU Utilization in the tree

view.
